Petri Net-based Power CPS Network Attack and Impact Modeling

With the increase of the connectivity and automation of smart grids, the scale and complexity of it have multiplied, which makes the opportunities for cyber-attacks in smart grids increasing. This paper analyzes the architecture and interaction of power cyber-physical system, and uses time-petri net as a modeling method to model the means of attack and attack information transmission route in the power cyber-physical system, to study the possible ways of attacks and the impacts.
